How can I get skills in Windows administration

I don't have experience in windows environment but I don't know where to start I do have CCNA and it does not help a lot in my work in IT , I really need more skills and knowledge , but I am unable to find a way to get skills by my own.
Is there any school or certification , home lab maybe .... any suggestion to get experience?
